2 buffer and backup batteries, which allow to regulate the charge and to store the energy harvested by our solar panels:

Sustain 2

We pay utmost attention to the protection of these precious devices during the expedition. Cruise speeds easily exceeding 40 km/h under good conditions, and the rough surface of the icecap (sastrugis) put all equipment to a test. But electronic devices are particularly vulnerable yet at the same time crucial for our safety as we use them for navigation, weather updates and general communication. Redundancy in our power sources, power storage, but also in our devices will help us to ensure these vital functions in case of potential failure.

Carnets d'Adventures, the magazine of "fair-mean" journeys, in the nature, on foot, bike, kayak, ski, paragliding, horse, roped party... with bivouac, going from a few days to several years, becomes partner of Wings Over Greenland II.

This magazine that celebrates its 9 years existence, became in France (in Belgium and Switzerland too) a major reference for not motorized travelers. Quarterly read by several tens of thousand outdoor sports activities amateurs, extended on the net by the www.expemag.com website (approximately 3000 unique / day visitors), Carnets d'Adventures is different from other magazine by its very complete technical files and equipment trials.

Finse,
Hardangerjökulen and Skarvheimen massifs,

March
1 – 9, 2013

Every
winter since 2007, we make a trip to Finse in the south of Norway for
kiting. Our first journeys there were the opportunity to prepare a
south-north kite-ski crossing of Greenland. An expedition we realized
in May 2008: 2250 km across the Greenland ice sheet in 31 days.
Since then, we never stopped to return to this place of Norway,
totally convinced that Finse is one of the best European spots for
snowkiting as we like it, free ride and touring style : sure snow
coverage, almost permanent wind, a playful, hilly terrain, neither
too gentle nor too pronounced, vast expanses of untouched terrain...
An explosive cocktail for those who wish to really combine
snowkiting, freeriding and endless spaces...

The
following acount is about our first test of the Flysurfer Speed
series kites and our impression of the 2 bigger wings that we are
going ot take on our next Greenland expedition, the Speed 4 10 m2
Deluxe and Speed 3 19 m2
Deluxe...

***

In
the South of Norway, the weather was incredibly good during the
entire month of February. It was not without a certain fatalism that
we take note of the weather reports announcing a change for the week
to come... Normal, in a way, the good weather had lasted too long
already...And
indeed, at our arrival at Finse on Saturday, March 1st,
a strong gale is raging. We have no other choice than to wait until
the next day for things to calm down for our first kite session, made
in Norway 2013.

On
Sunday, March 2nd, the wind exceeds 25 knots, and despite the
visibility getting better in the afternoon, it is not reasonable to
try our brand new Speed 4 10 m² Deluxe in these
conditions. No problem, we take our Beringer parawings out of our
quiver (open celll wings on which the bridles are directly connected
to a bar oriented perpendicularly to the leading edge, particularly
effective in stormy weather)... Invented in Germany, these wings are
used since a long time on polar expeditions, but also at Finse where
probably no less than 50 % of the parawing users worldwide are
concentrated ...

Despite
their rather basic appearence,
these sails have nevertheless excellent qualities in many situations
and are particulary pleasant and safe to fly in excessively strong
winds : it is then necessary to carve the skis pretty hard,
maintaining a very oblique position ... The exercise gets quickly
rather physical when looking for speed and sensations...

On
Monday, 3 and Tuesday, 4, the wind eased out sufficiently, so that we
could finally unpack our new toys. But the pale luminosity still
masks a lot of the surface texture which we discover to be very
sculptured by the wind, full of hard sastrugis. We do not remember
having seen comparable snow conditions on the Finsevatnet lake since
we know the area.

The
first time we finally
get
hands
on our Speed 4 10 m², we stay on the
Finse lake and on some slopes dominating its surroundings, but we
couldn’t
really switch
into high gear and take
advantage of the
full
potential of this new generation of kites
yet. Since then, a
nice session at
one of
our alpine home spotsin
Cervières,
French Alps allowed
us to
better appreciate this excellent wing.

The
next 3 days, the wind turned east
and south-east which is synonym for more stable conditions, very
beautiful days, intensely sunny, but also low winds. We took out the
big ones, our Speed 3 19 m2
got
unleashed, ready to reveal their full potential !

Wednesday,
an erratic breeze on the lake eventually convinces us to put the
skins on our skis in order to reach the heights of Hardangerjökulen,
a small icecap peaking at 1863 m. Small, only on the scale applicable
to nordic contries, but sixth biggest glacier of Norway with a
surface of 73 km². Cornelius, more realistic, skins up almost to the
top, to make sure to catch the wind. Mika thinks he can take
advantage of the light breeze blowing on the Middalen glacier, in the
hope to gain some height quickly and with less efforts... Wrong
idea... !

It
is necessary to say that we had never experienced a phenomenon as
strange as this one, the light catabatic creeping down the surface of
the glacier was clearly sufficient to make a kite of 12 m2
or even 10 m2
fly. Yet the thickness of the catabatic layer barely exceeded 5 m in
height. Above, the wing faints systematically. If the breeze was
sufficient to barely keep the sail just above the ground level, it
didn't allow the kite to raise. In every kite loop, the wing would
loose power and drop again. Mika persists in this hopeless task in
the expectation to find a stronger catabatic flow on the west side of
the glacier. He eventually gets grounded for good. Ready to give up
and return back home, he perceives the blue and white sail of
Cornelius far on the summit crest of Hardangerjökulen, changes his
mind, puts on the skins again, and climbs the Middalen glacier.

It
is already 16:30 when he finally
reaches the summit
crest, where the wind had sensibly picked up in the meanwhile.
Cornelius, has already left
off to kite
down one of the small
glaciers
in the northeast. The top of the icecap is
slightly undulated,
the landscape very
open,
and the view ranges
from the Hardanger
plateau to
the far
south and east, as
well as the mountains of Skarvheimen and even the Jötulheimen - peak
of Scandinavia in the north. Unexpectedly, the
surface of
the icecap is much
better than the hard
packed and rough
snow which covers
almost all of
the lower parts.Its
already two years
since we
last kited on the
summit of Hardangerjökulen. Last winter, the snow had been glazed
before our arrival there, and the winds had remained too strong to be
able to reach it
with these icy surface conditions...

glacier. In the background, the seemingly endless plateaus of Hardangevidda.

By
now, the sun is already low on the horizon and after a few tacks,
Mika pricks towards the northeast and kites down the Blaisen glacier,
in headwind. Once on its terminal part, where the slope gets pretty
steep, the kite suddenly moves by 120 degrees in the wind window,
switching at once from head- to tailwind. A sign that the rider has
just left the layer affected by the meteorologic wind and found again
the catabatic. After negotiating the bit tough exit from Blaisen in
tailwind, he finally loses the wind at the glacier front. Michael
packs the kite, and calculates his return route to make best use of
the slope and finish the last kilometers skating at nightfall, full
of good mood.

On
Thursday, March 7th,,
with same weather forecast and always no wind on the lake, we put on
the skins again. This time we climb the south slopes of the hills
dominating Finse , in the direction of Satehjellane mountains. 200
vertical meters above the village, we find light easterly winds. We
get out the big kites and play a moment on the heights of
Sanddalsnuten, but as soon as we lose a little altitude, the breeze
becomes erratic, sometimes non-existent.

But
finding the spot a little to small while the surrounding undulating
landscape invites to roam, we follow the temptation and venture
northward, unsure about the wind.

Monts Satehjellane

We
cross a first depression, a lake
shielded from the wind, as fast as possible and notice to our great
pleasure, that the little speed we gained in joining the bottom is
enough to slightly power up the 19 and to get us cross the
depression. Amazing!

For
one hour, we fight in an almost
non-existent wind, trying to round our kiteloops well while staying
as close as possible to the moraine ridges, diving from time to time
into little slopes to get across some shallow valleys and small
lakes. This way, we eventually reach the Klemsbu shelter, and the
Sankt Pål peak.

Hardangerjökulen massif.

We
are convinced, that in order to get back to Finse we would have to
pack the kites, as the valley we are about to follow seems entirely
shielded from the wind.

While
moving closer to the slope announcing the valley, we set ourselves an
ultimate point to reach by kite and where we are convinced we would
definitely lose the wind. But no ! The gentle breeze pouring down the
slope together with our slightly downward trajectory gives sufficient
power to our kites to continue.From
then on we try our best to keep the altitude, to avoid getting buried
in the valley, and notice that the wings really keep on flying. With
Sanddalsnuten behind us, we imagine for a moment that we would have
to go up the slope sailing into the wind in order to reach a small
pass that would allow us to get over to the windward side. One
tacking makes us aware of this laborious choice and of the strong
risk to get out of the wind in these feeble aerologic conditions. So
we resume again our tailwind course and finally realize happily that
the breeze here is sufficient to carry us across the crest of
Sanddalsnuten a little further south. Once there, we dive down a
frozen hillside making a few tacks, cross the high-voltage line and
pursue the descent to Finse in light tailwinds...

Throughout
the entire day, the behavior of the Speed 3 19 m2
left us really
amazed. It is obvious that we would not have been able to make this
days tour with a smaller kite. With sometimes very little wind, we
managed to make slow but efficient progress, doing long series of
kiteloops on the more favorable side, much helped by the ingenious
Infinity Bar, without ever completely losing the wind or "folding
the ears". As long as the sail is moving, even at very low
speed, the canopy remains inflated and extremely stable. At the end
of the loops, when the kite rises up again, it is a precious
advantage to be able to focus on the trajectory without having to
care about the risk of deflation. On the other hand, we had to
permanently pull on the back lines behind floaters in order to close
our manys loops of small diameter. Interestingly, every time we were
able to gain some speed, there was immediately a considerable
increase in power, making any kiteloops unnecessary.

On
Friday, 8, the sun still shines, and there is almost no wind at Finse
and on the lake. We are not sure where to go today. But looking
through the windows of our cabin, an observation suddenly puts an end
to our hesitation. 3 kiters are making their way up the Blaisen
glacier headed to the Hardangerjökulen.

Today,
the breeze is just sufficient to start right from the lake. We don't
ask for more ! Once again, we realize that even in very low winds,
the Speed 3 19 m2
already nows to unfold
its full potential. It takes us only a few minutes and about ten
tacks, where we needed at least twice more the previous years, to
reach the eastern border of the Blaisen glacier. A feeling of
outrageous efficiency ! This kite has surprising power reserves, we
only need to pick up a minimum of speed to be able to power it up and
lock it in in the wind window. By the way, the headwind tacks are
distinct with really high windward angles.

In
the lower part of Blaisen, a catabatic cancels the meteorologic wind
resulting in a zone of turbulences. Some loops allow to pass the last
one of the 3 kiters spotted from our cabin one hour before, a group
of pleasant Czechs, buried for some time in this area of complex
aerology. But a little higher up on the curved glacier, the catabatic
strengthens the meteorolgic wind and locally we observe even drifting
snow. In 2 tackings, we pass Venina, the girl of the Czech group, and
join her friend Pavel who just made it to the summit a little before
us. On arriving there, Ronny Finsaas, an experienced local kiter,
appears out of thin air, racing up the glacier with his handle kite
on 50 meters lines.

We
set sail towards the south dome of the icecap, a few kilometers away,
to admire the view on the Hardangervidda plateaus. On our way back,
we just manage to return to the main summit in fainting wind. For a
moment we hesitate to head west-northwest, by crossing the slopes
linking the top of the Middalen glacier to the domes of the
Hardangerjökulen. We try and it seems to work, but without any
guarantee in case the wind weakens. Finally, we give up and cross
towards the northeast, 50 meters below the summit. There, as two days
ago, only a a thin sheet of cold air creeps down the summit slopes.
We make some effort to progress crosswinds, but with no better
results than 2 days before. The lesson is learned, this time we give
up.

On
Saturday, March 9th, the clouds are back, the visibility poor, and
the easterly wind remains pretty weak. We take advantage to test the
Speed 3 19 m2 with
46 m lines, instead of the 21 m supplied with the kite. In 2008,
during our south-north Greenland crossing, we had tested lines of 40,
50, 60 and even 100 Meters and quickly adopted the first 3 lengths
systematically for our medium and large-sized kites. The interest had
been immediately obvious. A larger wind-window allowing bigger, more
powerful loops, the need to do less of them, while the kite stays
higher above ground. In consequence, the risk of deflating the kite
or tangling the bridles and lines in sastrugis is greatly reduced.
Fewer turns in the case of figure 8 patterns means also a reduced
loss of proper speed of the kite, and allows one to catch stronger
winds at 40, 50, even 80 m over the icecap where the wind speed is
less influenced by the surface roughness, which is slowing down the
flow of the catabatics close to the ground.

With
line this long, the Speed 3 19 m2
seems even more
stable, if this possible at all. Yet gets inevitably less reactive.
After tacks and turns, the sail needs a little more time to be
well-settled, yet again, once locked in, does not move any more...

This
evening, we take the train that brings us back to Oslo, but our
spirits still hang around the Hardangerjökulen slopes. The week was
excellent. We encountered all of the possible weather conditions a
stay in Norway can hold in store, yet had the opportunity,
repeatedly, to do what we appreciate most, climb the summits and do
amazing tours. Last, but not least, we got hands on our new kites and
were able to get a glimpse of their excellent potential for our next
project in Greenland...

Tuesday, February 26, 2013

We
have arrived in the world of snowkiting and this lively community by
the way of polar expeditions. To add a very technical activity, as
well as the delights of speed and gliding, to the repetitive and
laborious activity that are often at the core of the progression on
long polar skiing expeditions, was our main motivation. But time
passing, we got hooked and we have meanwhile become real snowkiters.
At least almost, as we still stay a little away from the busy and
small spots of our regions ! Yet every week during winter, we get our
kites out to do some backcountry riding in mountains.

But
we never forget our first "loves" above all that. Since one
year already we are planning a huge expedition through the polar
territories again. To be revealed soon !

Anyway,
we are more experimented kiters today than we were during our
previous Greenland crossing, and we also acquired some practical and
theoretical working knowledge of the peculioar aerology of polar
icecaps. It was thus natural to completely rethink the choice of the
kites in order to find the most adapted tools for this new project.

We
know today that the success of large-scale snowkite expeditions is
based on some simple criteria:

Naturally,
it is necessary to be capable to progress by kite in all conditions.
But contrary to the idea one may get, it is particularly important to
be able to make ground in low, or even very low, winds.

An expedition needs
of course a complete and effective
quiver to progress in winds ranging from 7 knots to about 40 knots.
However, it is of advantage to limit the number of kites ! Less with
the objective to reduce the weight and volume embarked on the
expedition, but rather to simplify the essential and permanent
question of the appropriate choice of kite size. If a single kite
corresponds to a given wind speed, and if the wind range of the
different kites does not overlap substantially the choice is so much
easier.

Indeed,
the daily gain in distance is not determinated by the maximum- but
rather by the average-speed the team is capable to maintain. Making
the right choice of kite size all the time (to know how to delay a
desire for change or, on the contrary, operate an efficient change
when necessary) is as important as knowing to get the best out of a
given kite in the low, medium and high wind speed range. Having no
option to hesitate between two potentially good kites surely
increases the efficiency.

Add
a daily kiting routine of 10 hours or more, in a hostile and very
isolated environment, and this during more than 50 days, it is normal
to consider the piloting comfort as a parameter of primordial
importance. It will help to save energy, increase the efficiency and
results in a reduced risk.

However, the quest for comfort should
not impair the kites performances such as the progression at high
speeds, the ability to maintain a heading in difficult going
(headwind, downwind), and a homogeneous performance of the kite over
its entire wind range including the lower and higher limits. For the
bigger kite to be used in winds lower than 10 knots, its capacity to
take off and to relaunch again, to fly and to generate pulling power
in very light wind is obviously of primary importance.

Flysurfer Speed 4 10 Deluxe

Finding
the best compromise between piloting comfort and flying performances
is not a simple task, because these two parameters are often
antagonistic. Flysurfer, proposing kites with both, fast and stable
profiles thanks to the closed cells design, and a pleasant and safe
control thanks to an unbelievably effective depower, seems the kite
maker coming closest to the perfect mix which we are looking for. By
opting for Speed 3rd and 4th generation, for winds lower than 25
knots, we should have adequate tools for our ambitions...

If
it is more than likely that we shall lose a little comfort in ground
handling during stops and while packing the kites due to the closed
cell design. Yet this is the price to pay for their stability during
the progressiion, and the efficiency of the depower combined with
their wide wind speed range, their capacity to sail upwind or lock in
in a given position of the wind-window. The power reserve of the
Speed 3 19 m2 and
its capacity to relaunch even in very low, wind will be among the
many advantages which should help to increase our average progression
on the ice, without making too much compromises on the piloting
comfort.

The
English company 'Snowsled', specialized in the conception of pulkas and equipment for polar expeditions, was one of the "historic"
partners of Wings Over Greenland 2008 and the first one to show us
its confidence.

Roger
Daynes, the owner of the company, kindly agreed that Snowsled is again going to be our partner in 2014 and will support the expedition with the new Ice BlueExpedition pulkas (the bigger sister of traditional Ice Blue Trail) as
well as the associated bags ans ajustable straps developed by Snowsled.

We plan to use use them once again in a catamaran configuration, where 2 pulkas are tethered together in parallel for increased stability when kiting at high speed. The circumnavigation project in 2014 will benefit from the increased volume and load capacity of this new model to haul the estimated total of 300 kg of equipment and food, which we are going to take along with us.
